ALBERT B. SCHOFIELD, OF BROOKLYN, NEW YORK.

-WRENCH.

SPECIFICATION forming part of Letters Patent No. 506,832, dated October17, 1893.

Application filed February 29, 1892. Serial No 423,231. (No model.) 7

To all whom it may concern:

Be it known that I,'ALBERT B. SoHoFInLD, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful Improvementin Wrenches, of which the following is a specification.

My invention relates to a wrench in which a stock or handle is developedinto or provided with various shaped appendages adapting it to a varietyof uses in the arts.

Figure 1 is a view of the wrench in side elevation, and Fig. 2 is alongitudinal transverse section partly in elevation taken on the line0:, 0c of Fig. 1.

The stock or handle of the wrench is represented'by A and may be formedof iron, steel or other suitable material. At one end the stock A isprovided with a cross-head B, one end of the head being flattened, as isusual, for driving nails and the like and the opposite end of the headbeing provided with claws b for drawing nails, as is common.

In proximity to the hammer head B I provide one or more recesses forreceiving a nut. I have shown in the present instance three suchrecesses of diiferent sizes to accommodate different sized nuts incommon use. The larger of these recesses I form by extending a jaw alaterally from the stock at a suitable distance from the flattened endof thecross head, another I form by extending a jaw a laterally from thestock or handle A at a point a suitable distance from the base of theclaw end of the cross head and a third, still smaller, is formed in theouter face of the cross head. The first of these recesses is denoted byO, the second by C and the third by 0 In order to extend the adjustmentsof the stock to nuts of difierent sizes I further provide within theswelled end of the stock or handle a set of three rectangular openings,denoted by c, c and 0 respectively and in the present instance I haveshown their adjacent sides as merging together and forming onecontinuous opening through the handle, the said opening converging stepby step to form the difierent sizes. It is intended that the opening 0shall be smaller than the recess 0 in the head so that the tool will beprovided with six different sized openings for its adjustment to nuts.The opposite end of the stock or handle is conveniently provided with ascrew driver D.

Along the opposite sides of the central portion of thestock or handle A,I form shallow recesses E and E between which there is 10'- cated acomparatively thin web of material 6.

The handle is graduated to form a measure, as clearly indicated in Fig.1, and a series of perforations e is formed along the Web portion e andat intervals apart correspond ing to intervals on the graduated scale,for purposes of sweeping circles by placing a marking device through oneof the perforations e and centering the tool by a pin or other pointeddevice inserted through a perforation b in the head. I also provide thehead with another larger perforation 19 which together with theperforation b may be utilized to receive wires or nails of diiferentdiameters for purposes of bending or breaking them.

When the tool is formed of a single piece of metal it may be cast orforged into the shape described.

The wrench as thus constructed maybe used as a hammer, screw driver,compass, measure and wire breaking device, the metal being so disposedas to render the tool strong and handy for these various purposes.

What I claim is- 1. The wrench consisting of a single piece of materialcomprising a stock or handle de veloped at one end into pairs of jawsextending in opposite directions from the sides of the handle and fromthe end of the handle, a single portion extending across the end of thehandle forming in itself one of each pair of laterally extending jawsand both of the end jaws, said cross portion being flattened at one endto form a hammer and at its opposite end extended to form a claw,substantially as set forth.

2. The wrench consisting of a single piece of material comprising astock or handle developed at one end into pairs of jaws extending inopposite directions from the sides of the handle and from the end of thehandle, a single portion extending across the end of the handle formingfour jaws; a hammer head and a claw, the handle being out away along itscentral portion leaving a web through which a series of holes is formedcorresponding to a scale and the end jaw ofthe wrench
